Aside from the 1200, all the Nissan struts use the same diameter insert. The only difference in any of them is length. If you can disassemble the strut, and tell me how deep the strut housing is, I can tell you what insert will fit it.

Option 2, Get inserts for a '79-83 280ZX. They are generally the shortest insert, and you can use a spacer in the bottom of the tube to take up the slack.

Thanks guys. Especially you John!I have now ordered the last 4 ACDelco front strut cartridges in existence for the 200SX. (2 for now. 2 for spares down the road.)All that's left is one Gabriel and one Nissan oem strut. (the Nissan one is in Georgia.)

Aggh. RockAuto sent me 4 Rears!I am one step closer to getting front strut cartridges though. I found that by cross referencing Gabriel part numbers that the 200SX, 68-70 510, and 77-80 810 all use the same front cartridge.
